Dynamic Surface Reconstruction of Amphoteric Metal (Zn, Al) Doped Cu₂ O for Efficient Electrochemical CO₂ Reduction to C₂₊ Products.

ABSTRACT: The recognition of the surface reconstruction of the catalysts during electrochemical CO₂ reduction (CO2RR) is essential for exploring and comprehending active sites. Although the superior performance of Cu-Zn bimetallic sites toward multicarbon C₂₊ products has been established, the dynamic surface reconstruction has not been fully understood. Herein, Zn-doped Cu₂ O nano-octahedrons are used to investigate the effect of the dynamic stability by the leaching and redeposition on CO2RR. Correlative characterizations confirm the Zn leaching from Zn-doped Cu₂ O, which is redeposited at the surface of the catalysts, leading to dynamic stability and abundant Cu-Zn bimetallic sites at the surface. The reconstructed Zn-doped Cu₂ O catalysts ac
